An access point may advertise (e.g., broadcast) identifying information (e.g., a neighbor report and access point capability information) on a dedicated channel in a wireless network. The identifying information may include information about neighboring access points in the wireless network. The neighboring access points may operate on the dedicated channel, a different primary operating channel, or a combination thereof. A station entering the wireless network may scan the dedicated channel to detect the identifying information from the access point to aid relatively quick discovery of the neighboring access points without scanning multiple channels.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method comprising: generating identifying information at an access point, the identifying information including at least one of a neighbor report or access point capability information, wherein the access point capability information is carried in a fast initial link setup (FILS) indication element according to an Institute of Electrical and Electronics Engineers (IEEE) 802.11ai protocol; and broadcasting the identifying information via a dedicated channel in a wireless network, the dedicated channel comprising a common channel that is shared by multiple access points in the wireless network to broadcast neighbor reports.
2. The method of claim 1 , wherein the neighbor report includes a reduced neighbor report according to the IEEE 802.11ai protocol.
3. The method of claim 1 , wherein the access point capability information includes access point security information associated with the access point and higher layer capability information indicating higher layer capabilities of the access point.
4. The method of claim 1 , wherein the dedicated channel comprises a particular channel in a set of non-overlapping channels.
5. The method of claim 1 , wherein the access point comprises an IEEE 802.11 ai access point, and wherein the wireless network comprises an IEEE 802.11 wireless network.
6. The method of claim 5 , wherein the IEEE 802.11ai access point comprises a dual-band access point.
7. The method of claim 5 , wherein the IEEE 802.11ai access point comprises a single-band access point.
8. The method of claim 1 , wherein the neighbor report includes a list of nearby access points in the wireless network.
9. The method of claim 8 , wherein each access point in the list of nearby access points is operating on a distinct channel.
10. The method of claim 1 , wherein the neighbor report is included in one of a beacon frame broadcasted from the access point via the dedicated channel, a FILS discovery frame broadcasted from the access point via the dedicated channel, or a probe response from the access point.
11. The method of claim 1 , further comprising: scanning the dedicated channel for a particular time period to detect one or more broadcasted neighbor reports from one or more corresponding access points prior to the broadcasting the identifying information; wherein the access point determines whether to suppress the broadcast of the identifying information based on corresponding signal strengths of the one or more broadcasted neighbor reports.
12. The method of claim 1 , further comprising broadcasting a second neighbor report and a second access point capability information on a primary operating channel of the access point.
13. The method of claim 1 , wherein a broadcast of a particular neighbor report from the access point is suppressed when a received signal strength of another neighbor report broadcasted from another access point satisfies a first threshold.
14. The method of claim 1 , wherein a broadcast of a particular neighbor report from the access point is suppressed when signal strengths of corresponding neighbor reports broadcasted from other access points satisfy a second threshold.
15. The method of claim 14 , wherein the signal strengths of corresponding neighbor reports correspond to at least three signal strengths of three corresponding neighbor reports.
16. An apparatus comprising: a processor; and a memory coupled to the processor, wherein the memory stores instructions that are executable by the processor to perform operations comprising: generating identifying information at an access point, the identifying information including at least one of a neighbor report or access point capability information, wherein the access point capability information is carried in a fast initial link setup (FILS) indication element according to an Institute of Electrical and Electronics Engineers (IEEE) 802.11 ai protocol; and broadcasting the identifying information via a dedicated channel in a wireless network, the dedicated channel comprising a common channel that is shared by multiple access points in the wireless network to broadcast neighbor reports.
17. The apparatus of claim 16 , wherein the neighbor report includes a reduced neighbor report according to the IEEE 802.11 ai protocol.
18. The apparatus of claim 16 , wherein the access point capability information includes access point security information associated with the access point and higher layer capability information indicating higher layer capabilities of the access point.
19. The apparatus of claim 16 , wherein the neighbor report is included in one of a beacon frame broadcasted from the access point via the dedicated channel, a FILS discovery frame broadcasted from the access point via the dedicated channel, or a probe response from the access point.
20. The apparatus of claim 16 , wherein the operations further comprise: scanning the dedicated channel for a particular time period to detect one or more broadcasted neighbor reports from one or more corresponding access points prior to the broadcasting the identifying information; wherein the access point determines whether to suppress the broadcast of the identifying information based on corresponding signal strengths of the one or more broadcasted neighbor reports.
21. A non-transitory computer-readable medium comprising instructions that, when executed by a processor, cause the processor to: generate identifying information at an access point, the identifying information including at least one of a neighbor report or access point capability information, wherein the access point capability information is carried in a fast initial link setup (FILS) indication element according to an Institute of Electrical and Electronics Engineers (IEEE) 802.11 ai protocol; and initiate a broadcast of the identifying information via a dedicated channel in a wireless network, the dedicated channel comprising a common channel that is shared by multiple access points in the wireless network to broadcast neighbor reports.
22. The non-transitory computer-readable medium of claim 21 , wherein the neighbor report includes a reduced neighbor report according to the IEEE 802.11 ai protocol.
23. An apparatus comprising: means for determining a signal strength of at least one broadcasted neighbor report on a dedicated channel in a wireless network, the dedicated channel comprising a common channel that is shared by multiple access points in the wireless network to broadcast neighbor reports; and means for broadcasting identifying information via the dedicated channel in response to a determination that the signal strength fails to satisfy a threshold, the identifying information including at least one of a neighbor report or access point capability information, wherein the access point capability information is carried in a fast initial link setup (FILS) indication element according to an Institute of Electrical and Electronics Engineers (IEEE) 802.11 ai protocol.
24. The apparatus of claim 23 , wherein the neighbor report includes a reduced neighbor report according to the IEEE 802.11ai protocol.
25. The apparatus of claim 23 , wherein the dedicated channel comprises a particular channel in a set of non-overlapping channels.
